Ladies and Gentlemen:

We have acted as counsel to Woodward Inc., a Delaware corporation (“Woodward”), in connection with the transactions contemplated by the Agreement and Plan of Merger, dated as of January 12, 2020 (the “Agreement”), by and among Woodward, Genesis Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Woodward (“Merger Sub”) and Hexcel Corporation, a Delaware corporation (“Hexcel”). Pursuant to the Agreement, Merger Sub will merge with and into Hexcel (the “Merger”) with Hexcel surviving the Merger. At your request, and in connection with the filing of the Form S-4 (including the joint proxy statement/prospectus forming a part thereof, the “Registration Statement”), we are rendering our opinion concerning certain U.S. federal income tax matters. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Agreement.

In providing our opinion, we have examined the Agreement, the Registration Statement, and the other documents described therein and such other documents as we have deemed necessary or appropriate for purposes of our opinion. In addition, we have assumed that (i) the Merger will be consummated in accordance with the provisions of the Agreement and as described in the Registration Statement (and no transaction or condition described therein and affecting this opinion will be waived by any party), (ii) the statements concerning the Merger and the parties thereto set forth in the Agreement and in the Registration Statement are true, complete and correct, (iii) the statements and representations made by Woodward, Merger Sub and Hexcel in their respective officer’s certificates dated as of the date hereof and delivered to us for purposes of this opinion (the “Officer’s Certificates”) are true, complete and correct as of the date hereof and will remain true, complete and correct at all times up to and including the Effective Time, (iv) any such statements and representations made in the Officer’s Certificates “to the knowledge of” any person or similarly qualified are and will be true, complete and correct without such qualification, (v) the Merger will qualify as a statutory merger under the DGCL, and (vi) Woodward, Merger Sub, Hexcel and their respective subsidiaries will treat the Merger for U.S. federal income tax purposes in a manner consistent with the opinion set forth below. If any of the above described assumptions is untrue for any reason or if the Merger is consummated in a manner that is different from the manner described in the Agreement and the Registration Statement, our opinion as expressed below may be adversely affected.

Based upon and subject to the foregoing, we are of the opinion that, under currently applicable U.S. federal income tax law, the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

We express no opinion on any issue relating to the tax consequences of the transactions contemplated by the Agreement or the Registration Statement other than the opinion set forth above. Our opinion is based on current provisions of the Code, Treasury Regulations promulgated thereunder,
